To give a Bai'a for not to flee during a battle

Narrated Ibn `Umar:

When we reached (Hudaibiya) in the next year (of the treaty of Hudaibiya), not even two men amongst us agreed unanimously as to which was the tree under which we had given the pledge of allegiance, and that was out of Allah's Mercy. (The sub narrator asked Naf'i, "For what did the Prophet (ﷺ) take their pledge of allegiance, was it for death?" Naf'i replied "No, but he took their pledge of allegiance for patience.")

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، قَالَ قَالَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ رَجَعْنَا مِنَ الْعَامِ الْمُقْبِلِ فَمَا اجْتَمَعَ مِنَّا اثْنَانِ عَلَى الشَّجَرَةِ الَّتِي بَايَعْنَا تَحْتَهَا، كَانَتْ رَحْمَةً مِنَ اللَّهِ‏.‏ فَسَأَلْتُ نَافِعًا عَلَى أَىِّ شَىْءٍ بَايَعَهُمْ عَلَى الْمَوْتِ قَالَ لاَ، بَايَعَهُمْ عَلَى الصَّبْرِ‏.‏

Narrated `Abdullah bin Zaid:

that in the time (of the battle) of Al-Harra a person came to him and said, "Ibn Hanzala is taking the pledge of allegiance from the people for death." He said, "I will never give a pledge of allegiance for such a thing to anyone after Allah's Messenger (ﷺ) ."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا عَمْرُو بْنُ يَحْيَى، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ ـ رضى الله عنه ـ قَالَ لَمَّا كَانَ زَمَنَ الْحَرَّةِ أَتَاهُ آتٍ فَقَالَ لَهُ إِنَّ ابْنَ حَنْظَلَةَ يُبَايِعُ النَّاسَ عَلَى الْمَوْتِ‏.‏ فَقَالَ لاَ أُبَايِعُ عَلَى هَذَا أَحَدًا بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم‏.‏

Narrated Yazid bin Ubaid:

Salama said, "I gave the Pledge of allegiance (Al-Ridwan) to Allah's Messenger (ﷺ) and then I moved to the shade of a tree. When the number of people around the Prophet (ﷺ) diminished, he said, 'O Ibn Al-Akwa` ! Will you not give to me the pledge of Allegiance?' I replied, 'O Allah's Messenger (ﷺ) ! I have already given to you the pledge of Allegiance.' He said, 'Do it again.' So I gave the pledge of allegiance for the second time." I asked 'O Abu Muslim! For what did you give he pledge of Allegiance on that day?" He replied, "We gave the pledge of Allegiance for death."

حَدَّثَنَا الْمَكِّيُّ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا يَزِيدُ بْنُ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ ـ رضى الله عنه ـ قَالَ بَايَعْتُ النَّبِيَّ صلى الله عليه وسلم ثُمَّ عَدَلْتُ إِلَى ظِلِّ الشَّجَرَةِ، فَلَمَّا خَفَّ النَّاسُ قَالَ ‏"‏ يَا ابْنَ الأَكْوَعِ، أَلاَ تُبَايِعُ ‏"‏‏.‏ قَالَ قُلْتُ قَدْ بَايَعْتُ يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ وَأَيْضًا ‏"‏‏.‏ فَبَايَعْتُهُ الثَّانِيَةَ،‏.‏ فَقُلْتُ لَهُ يَا أَبَا مُسْلِمٍ، عَلَى أَىِّ شَىْءٍ كُنْتُمْ تُبَايِعُونَ يَوْمَئِذٍ قَالَ عَلَى الْمَوْتِ‏.‏

Narrated Anas:

On the day (of the battle) of the Trench, the Ansar were saying, "We are those who have sworn allegiance to Muhammad for Jihaid (for ever) as long as we live." The Prophet (ﷺ) replied to them, "O Allah! There is no life except the life of the Hereafter. So honor the Ansar and emigrants with Your Generosity."

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ حُمَيْدٍ، قَالَ سَمِعْتُ أَنَسًا ـ رضى الله عنه ـ يَقُولُ كَانَتِ الأَنْصَارُ يَوْمَ الْخَنْدَقِ تَقُولُ نَحْنُ الَّذِينَ بَايَعُوا مُحَمَّدَا عَلَى الْجِهَادِ مَا حَيِينَا أَبَدَا فَأَجَابَهُمُ النَّبِيُّ صلى الله عليه وسلم فَقَالَ اللَّهُمَّ لاَ عَيْشَ إِلاَّ عَيْشُ الآخِرَهْ فَأَكْرِمِ الأَنْصَارَ وَالْمُهَاجِرَهْ

Narrated Mujashi:

My brother and I came to the Prophet (ﷺ) and I requested him to take the pledge of allegiance from us for migration. He said, "Migration has passed away with its people." I asked, "For what will you take the pledge of allegiance from us then?" He said, "I will take (the pledge) for Islam and Jihad."

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، سَمِعَ مُحَمَّدَ بْنَ فُضَيْلٍ، عَنْ عَاصِمٍ، عَنْ أَبِي عُثْمَانَ، عَنْ مُجَاشِعٍ ـ رضى الله عنه ـ قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم أَنَا وَأَخِي فَقُلْتُ بَايِعْنَا عَلَى الْهِجْرَةِ‏.‏ فَقَالَ ‏"‏ مَضَتِ الْهِجْرَةُ لأَهْلِهَا ‏"‏‏.‏ فَقُلْتُ عَلاَمَ تُبَايِعُنَا قَالَ ‏"‏ عَلَى الإِسْلاَمِ وَالْجِهَادِ ‏"‏‏.‏
